Abstract: An experiment with the aim to determine the socalled radiation damage function in gold is described. The damage function $\nu$ (T) is defined as the number of stable Frenkel defects produced at low temperatures by a primary atom to whom the energy T is transferred by irradiation with fast particles. A stack of identical gold foils was irradiated with high energy protons and $\alpha$-particles. Traversing the foils the particles are slowed down and therefore each foil is irradiated with a different mean particle-energy. The measurement of the electrical resistance change of each foil gives the total number of defects from which the damage function can be calculated. Large experimental and theoretical difficulties appeared: One of the main experimental difficulties e.g. was the nonuniformity of the foilthickness which gave a large error in calculating the number of defects from the resistance change in each foil. Furthermore, large corrections for increased defectproduction by particles scattered by large angles had to be made. Therefore the values and the energy relationship of the damage function could not be determined with sufficientaccuracy.
